Nearly Half a Million UK Homes Now Solar Powered

Consumers unhappy with energy supplier should switch to solar

Latest data from DECC on PV installations[1] shows that nearly 460,000 homes across the UK now have solar panels. Together the households have a combined peak capacity of 1.3GW, making domestic solar the largest sub-sector of the solar market. The figures show that nearly half a million UK homes are now much less exposed to the frustrations expressed by MPs this week to the 'Big 6' energy bosses, over large and unpredictable energy bill increases.

Due to massive international production volumes and major efficiencies achieved by the UK industry, the cost of installing solar has dropped exceptionally fast. When the Feed-In Tariff scheme began in 2010 domestic solar panels attracted 43p for every unit of power they generated. Today domestic solar attracts a much lower 14.9p/kWh - a massive drop of 65% in 3 years, yet returns remain steady. The Solar Trade Association's 'calculator' shows that homes installing a 4kW(p) system today could expect returns of around 12% and payback within 8 years.

STA CEO Paul Barwell said; "Barely a day goes past without widespread anger about ever-rising energy bills. Nearly half a million UK homes are now much less exposed to frustrating energy bill rises because they have chosen to go solar. It's a particularly clever choice right now because the returns are excellent. People who are fed up with their energy supplier could do no better than to switch to supplying themselves with solar power on their roof.

The more people that invest in solar power today, the quicker the price comes down tomorrow. We need to keep going down this path until solar power is cheaper than retail electricity prices and eveyone can have access to cheap, green power and stable energy bills."

Renewables are now giving the customer the real option to switch away from environmentally damaging and increasingly scarce fossil-fuels. The old energy sources are running out and putting our future at risk - switch to solar!"

Research shows that the majority of people who invest in solar power are motivated to make efficiency changes to their homes and change the way they use energy, saving more money. [2]

The Solar Trade Association wants to see 1 million solar roofs across the UK achieved in 2015. At current installation rates, around 100,000 solar pv systems are being installed in the UK every year. If this market could be doubled the 1 million home milestone could be achieved in 2015. The more solar panels are installed, the faster the price of solar falls, along with FIT support. The Solar Trade Association is confident domestic solar will be able to compete with retail electricity prices by the end of the decade. Thereafter all UK consumers will have the choice to self-supply more cheaply than buying power off the grid. The Feed-In Tariff, which supports solar power, makes a modest draw on energy bills at £7 per household this year [3].

The STA is developing its own online platform to share its expertise on solar with the public. YourRoof.Info provides practical expert advice about going solar and includes the STA's 'calculator' so householders can estimate their returns from investing in solar today. [4]

2. Good Energy Feed-In Tariff Report, 2011. Survey of 500 microgeneration customers shows two thirds changed the way they used energy. 60% undertook further energy efficiency measures. 55% reduced energy consumption - and a quarter by over 20%.

3. According to DECC, the Feed-in Tariff for small scale renewable electricity accounts for £7 on the average bill in 2013. This is out of the average bill of £1,267 overall.

RBI Solar - Dahlia Has You Covered

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
